From the foregoing it will be apparent that the present invention provides a new and improved form of seal for containers which is so constructed that the sealing element will be securely held in place and an air tight seal provided.

It is to be understood that the invention is not limited to the construction herein shown but that it may be provided in other forms without departing from the spirit and scope of the appended claims.

Having thus described the invention, what is .claimed as new, is:

vals in the angular wall and extending into said bead.

2. A seal for containers comprising a disk-like member having its main body portion disposed in one plane, an annular flange defining the peripheral edge of said main body portion, said flange being disposed in a parallel, but different plane from that of the main body portion, an angularly disposed wall connecting the annular flange with the main body portion, a bead formed in said main body portion adjacent the angular wall, and a plurality of depressions formed at spaced intervals in said angular wall and extending into said bead.

3. A seal for containers comprising a disk-like member having its main body portion disposed in one plane, an annular flange defining the peripheral edge of said main body portion, and an angularly disposed wall connecting said flange with said body portion and maintaining said main body portion and said flange in spaced relation, said angularlydisposed wall having a plurality of indentations therein arranged in spaced relation to one another.
